An investment plan for low-emission rice production in the Mekong River Delta region in support of Vietnam's Nationally Determined Contribution to the Paris Agreement
Rice production is integral to agriculture and food security in Vietnam, but it also contributes greenhouse gas emissions. In 2010, paddy rice production emitted 44.61 million tons carbon dioxide equivalents (MtCO2e), 18% of total national GHG emissions. A variety of options to mitigate GHG emissions from paddy rice show promise and will contribute to implementing Vietnam’s Nationally Determined Contribution (NDC) and green growth strategies. One of the most promising options is alternate wetting and drying (AWD), a technique in which fields are allowed to dry out to a certain point before irrigation instances. This paper focuses on the Mekong River Delta region, which produces more than 50% of total rice production and 95% of rice exported from Vietnam. This study employs a literature review, a study of promising GHG mitigation options, and an analysis of cost and benefits of AWD to develop an investment plan for AWD in the Mekong River Delta.
